This post has a free printable for Minnie and Moo Go to the Moon. Another hilarious and silly book in the Minnie and Moo series, this story is about the two cows taking the farmer’s tractor and flying it through the air. Did they fly through outer space? Minnie thinks they are on the moon, and Moo doesn’t quite agree. Pigs fly, eggs rain down, and the tractor gets stuck in the pond. The farmer only sees two cows eating grass when he finally finds out what happened. He keeps staring at the cows. Why? One of the cows is still wearing one of his boots. This book is such fun for beginning readers.
